JOSHUA O. CENTER, OF HAYNESVILLE, ASSIGNOR` OF ONE-HALF TO LEWIS MAYO, OF'LEAVENWORTH, KANSAS.

`SPECIIFICA'IIOhT forming part of Letters Patent No."284,378, dated September 4 i883.

To @ZZ whom t may concern/,-

` Be it known that I, JOSHUA C. CENTER; of Haynesville, in the county of Pratt and State of Kansas, have invented a new and useful Improvement in Seed-Drills, of which the following is a full, clear, and exact description.

Reference is to loe had to the accompanyingV drawings, forming part of this specification, in which similarletters of reference indicate corresponding parts in all the gures.

Figure 1, Sheet 1, is a planview of my improvement, parts being broken away. Fig. 2,

`Sheet I, is a side elevation of the same, partly of the same, taken through the broken line c z z, Fig. 5. Fig. 7, Sheet 2, is a sectional end elevation of ,the sliding gage, taken through the line w w, Fig. 6. Fig. 8, Sheet 2, is asectional side elevation of the-'sliding gage, taken through the line un, Fig. 7. Fig. 9, Sheet 2, is a side` elevation of the guard-plate for the seed-dropping cylinder. Fig. 10, Sheet 2, is a side elevation of the coupling-hinge.

rIhe object of this invention is to facilitate the drilling of seed, and also to promote convenience in operating and adjusting seeddrills.

A represents the forward frame, `and B the y rear frame, of my improved 'seeddrill-`, which frames are connected by the hinges C D. rlhe forward straps,'O, of the hinges are bolted to the outer sides of the side bars of the forward frame, A, with their rear ends projecting in the rear of thcends ofthe said side bars. The rear straps, D, of the hinges are bolted to the outer sides ofthe side bars of the rear frame, B, with their forward ends projecting in frontV of the said sidebars, so as tooverlap the outer sides of therear parts of the straps C. The

straps C, at their rear ends, and the straps D, at a little distance from their forward ends,A are ,y perforated to receive the ends of the shaft E,

which forms the pivots of the hinges.H To the soil.

Application ltiled February 13. 1883. (No model.)

inner sides of the projecting rear ends of the straps C are attached, or upon them are formed, journal-boXes F, to form wider bearings for the shaft E.

` Upon the upper and lower edges of the forward ends of the rear straps, D, are formed projecting lugs G, the ends of which are bent inward to overlap the inner straps, O, or the upper and lower sides of the side bars of the 6o forward frame, A, and serve as stops to limit the play of the hinges C D, and consequently of the frames A B. The upper lugs, G, have screw-holes formed through them to receive set-screws H, to serve as adjustable stops to 65 limit the descent of the rear part of the frame A, and consequently to limit the depth to which the runners connected with the said frame A, and hereinafter described, enterthe The runners are formed of the curved bars orcutters I, that enter the soil andv forni the channels to receive the seed, the top bars, J, and the standards K. The upper ends of the cutters I are bolted to the top bars, J, near 7 5 their forward ends. rlhe standards K are se cured at their lower ends to the rear ends of the' cutters I, and at their upper ends to the rear ends of the topbars, J. rI he rear ends of the cutters I are inclined to one side to form 8o mold-boards L, to move thev soil to one side, and thus open,y channels to receive the seed. Half of the cutters I have their moldfboards L formed upon the right-hand side, and the other half have their mold-boards L formed 85 upon the left-hand side, so that the sidedraft will be balanced and the machine will move forward in a straight line.`

To the opposite sides of the forward ends 'ofV the top bars, J, are attached straps M, 9o

which project in front of the said ends, and are bent outward and then forward, and have perforations formed in their endsl to receive pivots formed upon lugs N, formed upon the ends of plates O, attached to the lower part of 9 5 the rear side of the front cr`oss-bar of the frame A. rlhe frame A is made with a longitudinal bar, A', directly above 'each runner I J K. To the under side of the forward part of each bar A is attached the forward end of a spring, P, roo which is bent downward and rearward, and

its rear end rests upon a rub-plate, Q, attached to the upper side of the rear part of the top force the runners down to their places as soon A top bars, J, of the said runners and hold the as they have passed the obstruction.

'Ihe downward movement of the runners I J K is limited by a bar, R, placed beneath the rear parts of the top bars, J, or beneath arms formed upon the upper parts of the forward sides of the standards K, for the top bars, J, to rest upon and be secured to. The bar R has upwardly-projecting arms S formed upon or attached to its ends, which arms are attached to the rear parts of the side bars of the frame A. Upon the bar R are formed, or to it are.

attached, as many pairs of upwardly-projecting arms T as there are runners I J K, -which arms pass up upon the opposite sides of the runners from lateral movement.

4 The standards K are perforated longitudinally for the passage of the seed into the channels opened by the cutters I, and the upper ends of the said perforations are flared to adapt them to receive and work freely upon the conductor-tubes U. The upper parts of the tubes U are enlarged and have their rear parts cut away, and upon the shoulders thus.

formed are formed hooks V,to hook upon piv- 'ot-SHV, formed upon the sides of thelower ends of the chutes X, that receive the seed from the distributing mechanism and guide it into the tubes U.` The sides Y of the chutes X are eX- tended upward, and are'provided at their upper edges with perforated lugs to receive the screws or bolts by which they are secured to the bottom of the seed-box Z.

a is the cup that forms the bottom of the chamber that receives the. seed-dropping cyl! inder b. Upon the upper edge of the cup a are formed perforated lugs to receive the screws or bolts that secure the upper edge of the said cup to the bottom of the seed-box Z. The lower end of the cup a has a lip, c, formed upon it to overlap and rest upon the upper side of the upper part of the bottom of the chute X, to support the said lower end of the cup a in place. Upon the side edges of the cup a are formed flanges d, the upper ends or which are formed upon an angle to fit into angular recesses in the rear parts of' the sides Y of the chute X, to hold the said cup a from moving.

In the adjacent edges of the flanges d and sides Y arefor'med semicircular notches to form circular apertures `to receive the seed-dropping cylinder b, which is perforated longitudinally to receive and slide upon the shaft e.

The shaft e revolves in bearings attached to' theseed-box' Z or to the frame A, and to it is attached a feather, f, to enter a groove in the inner surface of the cylinder b, so that the said shaft will carry the said cylinder with it in its revolution. In the face of the cylinder b are formed rounded corrugations to take the seed from the feed-chamber and discharge it into the chute X.

In a recess in the inner side of one of the sides Y and flanges d is placed an annular plate, g, the inner edge of which is scalloped to correspond with and fit into the corrugations of the cylinder b, to prevent any seed from escaping at the end ofthe cylinder b as the said cylinder slides back and forth through the said plate, the said plate being carried around 4by and with the said cylinder in its revolution. Ihe other ends of the corrugations of the cylinder b are closed by the end of the cylinder h, which nts against the said end of the cylinder b, and is perforated longitudinally to receive the shaft e. The cylinder 7L is held from turning upon the shaft e by the feather i, formed upon the side of the said cyl-- inder h, and which enters a groove in the flanges, d of, the cup a. The inner end of the cylinder h is countcrsunk, as shown in Fig. 8, to' receive the featherf, when the cylinders b 7L are pushed forward.

'Ihelparts of the sides Y of the chute X above the cylinders b h are connected by a plate, j, Whicltforms the forward side of the feed-chamber. Upon the lower edge of theY plate j is formed a plate, k, which is 4curved in the are of the circumference of the cylinders b h. The lower edge of the plate j serves as a cut-off to prevent the corrugations of the cylinder b from carrying out any more seed than enough to fill them, and the curved plate k serves as a guard to keep the seed in the corrugations of the said cylinder until the said seed has been carried to a proper position to be discharged into the chute X. Vith this construction, by adjusting the cylinders b h, so that a greater or less part of the length of the corrugations of the cylinder b may be within the feedchamber, more or less seed will be distributed, as

may be desired, and by adjusting the said cylinder I) h, so that no part of the said corrugations will be within the said feed-chamber, no seed will be discharged, and the planter can be turned around and taken from place to place Without Waste of seed.

In bearings attached to the forward part of the seed-box support, or tothe frame A, slides a bar, Z, to which areattached, or upon which are formed, as many pairs of arms m as there are pairs of cylinders b hin the planter. The arms m of each pair are at such a distance apart as to receive the two cylinders b ZL between them, the said arms resting upn c61- IOO lars u, formed upon the outer ends ofthe said i other end of which is pivoted to-the lower endy of alever, p. The leverp is pivoted at its middle part to the lower'part of therear side of the seed-boXZ. Ihe upper part "of the lever p moves in a keeper, q, attached to the seed boX Z, and is provided with a clampingscrew, r, which passes through a' slot in the said keeper q, so that the said lever can be readily secured in place, holding the cylinders sei curely in any position into which they have v ro `been adjusted. l

The shaft e revolves in bearings attached to the supports of the seed-box Z or to the frame A, and is made in two parts placed in line with each other. rIo each part of the shaft e is attached a gear-wheel, s, the teeth of which mesh into the teeth of a corresponding gearwheel, t, attached tothe shaft E, sorthat the cylinder carrying shaft c will be driven from the shaft E. The shaft E revolves in bearings attached to the frame A, and is made in two parts placed in line witheach other. To each part of theshaft E, near its outer end, is attached a beveled-gear wheel, u, the teeth of which mesh intothe teeth of the beveledgear wheel o, attached to the forward end of the shaft w. The forward part of each shaft w revolves in bearings m, attached to the forward sitions as to follow the runners I J K and press cross-bar ofthe frame B. The rear end of each shaft w revolves in bearings y, secured by a clip, z, or other suitable means to the lower end of the lever 1, which' is fulcrumed to a support, 2, attached to the frame B. The upper part of the lever 1 `moves along a toothed catch-bar, 3, attached to the frame B, so that the said lever will be held securelyin any position into which it may be adjusted. i

To the shaft w, near its rear end, is4 attached a beveled-gear wheel, 4, the teeth of which mesh into the teeth of thevbeveledgear wheel 5, attached to the end of the sleeve 6. Ihe sleeve 6 is made in two parts and is placed upon the shaft 7, the ends of which are scf cured in `bearings in hangers 8, secured to the side bars of the frame B. Upon the `parts of the sleeve 6 are placed as many wheels 9 as there a-re runners I J K and pairs of cylinders Z) h, the said wheels being arranged in such pothe soil down upon the seed. The wheels 9 run loose upon the, parts of the sleeve 6, and

to them or to their hubs are pivotedpawls 10,

which engage with the ratchet-wheels 11, formed upon or attached to the parts of the said sleeve 6 so that eachwheel 9 will actindependently of theothers upon the part .of

. the sleeve 6 with which it is connected, and

one or more of `the said wheels may move slower than the others, or may stop, or be turned back without affecting the operation of the machine. With this construction the seed-dropping mechanism at each side of the machine will be run by its ,own drive-wheels, which prevents side draft and causesthe runners upon both sides of the drill-to work 4at the same depth.

` 12-is the drivers seat, which rests upon the horizontal bar 13, and is provided with a down- B. The inclined bar 17 is supported in position Aby a standard, 18, attached to it and to the rear cross-bar of the frame B. 'Ihe forward end of the horizontal bar 13 is attached to the upper end of the standard 19, the lower end of which is attached to inclined bar` 17, so that the seat will be Vfirmly supported.

20 is the foot-board or platform, which is secured to bar s 2l, attached to the cross-bars of the frame B.
